Hi all,

While reading an article today, I stumbled across the Xen project, which I
suppose is something like an open source VMWare. Could be interesting for
the hosting providers among you.

From their page (http://www.cl.cam.ac.uk/Research/SRG/netos/xen/):

Modern computers are sufficiently powerful to use virtualization to
present the illusion of many smaller virtual machines (VMs), each running a separate operating system instance. Successful
partitioning of a machine to support the concurrent execution of multiple
operating systems poses several challenges. Firstly, virtual machines must
be isolated from one another: it is not acceptable for the execution of
one to adversely affect the performance of another. This is particularly
true when virtual machines are owned by mutually untrusting users.
Secondly, it is necessary to support a variety of different operating
systems to accommodate the heterogeneity of popular applications. Thirdly,
the performance overhead introduced by virtualization should be small.
Xen is a virtual machine monitor for x86 that supports execution of
multiple guest operating systems with unprecedented levels of performance and resource isolation. Xen is Open Source software, released under the
terms of the GNU General Public License. We have a fully functional ports of Linux 2.4 and 2.6 running over Xen,
and regularly use it for running demanding applications like MySQL, Apache
and PostgreSQL. Any Linux distribution (RedHat, SuSE, Debian, Mandrake)
should run unmodified over the ported OS.
In addition to Linux, members of Xen's user community have contributed or
are working on ports to other operating systems such as NetBSD (Christian
Limpach), FreeBSD (Kip Macy) and Plan 9 (Ron Minnich). A port of Windows
XP was developed for an earlier version of Xen, but is not available for
release due to licence restrictions.
